I think I saw a large hoverfly? Approx 16mm long. Broad sripes to minmic a wasp. Large dark red eyes. Large reddish wings. Thorax seemed to be blue but maybe that was the light. Seen in Belair Park - not far from Dulwich Park - feeding on Creeping Thistle near a stream. Would be very interested to know name of hoverfly. Could not find in insect book. Thank you.
